Computers have had a great impact on society. Today computers are constantly becoming a part of everyday life. Computers are used in everything from the home PC or laptop to appliances such as microwaves and even our cars. Not only have computers had a great impact on our everyday life, but also on education and the workplace. Computers are used in our appliances, mobile phones, entertainment devices (such as DVD players) and others. It is almost impossible to get through one day without having some form of interaction with computers.
The Internet has had a huge impact on society. It provides information and services, as well as the ability to communicate people all around the world in variety of ways. These range from bulletin boards and chat rooms to voice conversations and video conferencing.
Around the world, the Internet is available to millions of people. Those who don’t have computer or access to the Internet at home will often have access at work or school, or even at the local library. Another added bonus of the Internet is that the majority of the information and services available are free.
The use of computers for educational purposes has been highly beneficial for those involved. From a primary school level, children are taught the basics of computer use, including the Internet. At high school, this continues as children become more and more proficient in using the computer.
It is a tertiary level though, that computers really come into use. News, assignments, tests, lecture notes etc. can be placed on the Internet for stu-

dents who live in remote areas and cannot travel to and from university or other tertiary institution each day. The idea of remote learning can also be applied to a primary school level.
Computers impact every part of our lives. From the home, to the workplace and in education, computers aid us to do what we want. In general, computers are beneficial to the tasks they are applied to. Although computers can cause some problems, such as unemployment and computer viruses, these are far outweighed by the benefits computers provide. Because of this, computers and technology will continue to have an increasing effect on society.
